Compact, globally certified wireless module series based on Nordic’s nRF52833 SoC, ideal for Bluetooth Low Energy, Zigbee and Thread applications where size, performance and reliability matter.
Featuring a 32-bit ARM® Cortex®-M4 CPU with 512 kB Flash and 128 kB RAM, this module supports Bluetooth 5.4 with Long Range (LE Coded PHY) and offers robust performance up to +105 °C. With its integrated PCB antenna and small 8.4 × 13.2 × 2.1 mm footprint, it is a perfect fit for space-constrained designs such as wearables, smart home devices and industrial sensors.
The module provides 18 GPIOs and a rich set of peripherals, including SPI, UART, I²C, PWM, ADC, I²S, NFC and USB, enabling flexible integration into a wide range of applications. It is fully certified for FCC, IC, CE, Telec (MIC), KC, SRRC, NCC, RCM and WPC, and is RoHS & REACH compliant, simplifying global product deployment and reducing time to market.
